Any help in obtaining either or both of the following Internal Political Boundary Maps as Digital Line Graphs (DLGs) instead of Bitmaps and Surveyor Type Legal Descriptions of the Internal Timezone Boundaries for the countries that are currently composed of multiple different timezones would be appreciated. Note that in the United States, this resolution has to go down to the county level, not just the state level, and possibly only a surveyor type legal description will do in cases like America/Indiana/Marengo where the current description in the timezone database is "part of Crawford County". I believe that I can easily get the county maps for all 50 states in this form, but I still need a surveyor type legal description of situations like this, and complete lists of counties by timezone in states that have more than one timezone. At the international level, I already located a copy of the 132 MB CIA Digital Line Graph database of the world that was released around 1990 under the Freedom of Information Act. It is composed only of line strokes, and my ultimate goal is polygons. So, the complete set of polygons that describe the current international boundary of each country and any internal regional timezones therein still have to be generated. Nevertheless, it does have international political boundaries as well as the boundaries of the states of the United States and the provinces of Canada. Other internal political boundaries within the various countries are missing, however, and the database also suffers from being out-of-date. It is circa 1989. Back on the good news front, in case it should prove useful, the database does have all significant rivers and other bodies of water down to a fairly fine level of detail. So, unless I find a better source of data, I need to bring this database up-to-date. To that end, I also need the current international political boundaries, probably in surveyor type legal descriptions, that correct all that has happened, especially in Europe and Asia, since the reunification of Germany and the breakup of the Soviet Union. At the internal political boundary level, I analyzed the timezone database and extracted a complete list of all countries (21 in all) that have multiple different current timezones, where "different" is defined as either a different current GMT offset and/or a different current daylight savings time rule. This list is summarized in the table that appears below. Within this table are 6 timezones 9.* australasia/New_Zealand 11.* europe:Norway 12.* europe:Portugal 14.* europe:Spain 20.* southamerica:Chile 21.* southamerica:Ecuador that were edited to have an asterisk ("*") appended to their number to indicate that it seems obvious where to draw a boundary between their constituent timezones. It seems obvious because the two distinct timezones involved in each case are distinguished from each other by one being on the mainland and the other being on an offshore island. This leaves the following 15 countries 1. africa:Zaire 2. asia:Indonesia 3. asia:Japan 4. asia:Kazakhstan 5. australasia:Australia 6. australasia:French_Polynesia 7. australasia:Kiribati 8. australasia:Micronesia 10. europe:Denmark 13. europe:Russia 15. europe:Ukraine 16. northamerica:Canada 17. northamerica:Mexico 18. northamerica:United_States 19. southamerica:Brazil where the exact boundary lines between their internal regional timezones must still be identified.
